I've got a mystery egg. I did vent checks last night and the only birds showing signs of laying are the bantam cochin and the salmon faverolle. I know who is laying the other 3 brown eggs. I have no idea where that white egg is coming from. I would suspect the cochin but it's a pretty decent sized egg for a bantam. I thought salmon faverolles laid pinkish eggs. I have 3 polish but they all still had dry vents even though they are old enough to be laying. The 2 EE's I have also both had dry vents but of are laying age as well. Any thoughts on who might be my white egg layer?
